My 03 TJ had spacers that are 1 7/8" or 2" thick on when I bought it and sat very level. I installed a winch plate and winch on the front bumper and now it's sagging a lot. I am looking at a set of 2" RE springs to replace my spacers but my question is should I do 2.5" up front and 2" in the back to counter the extra weight.
